I got diagnosed with prostate cancer Friday, June 13th, 2014. On September 17th of that year I got a test back telling me I was cancer free. The three months in-between were a crazy roller coaster ride with which about 180,000 men a year in America can identify.

Stiller, who was last seen on the big screen in Zoolander 2, is now cancer free but is still tested regularly, the Guardian reports.

He posted on Twitter today:

So, I had cancer a couple of years ago and I wanted to talk about it. And the test that saved my life. https://t.co/KWirBcRZ7D

I am not offering a scientific point of view here, just a personal one, based on my experience. The bottom line for me: I was lucky enough to have a doctor who gave me what they call a “baseline” PSA test when I was about 46. I have no history of prostate cancer in my family and I am not in the high-risk group, being neither — to the best of my knowledge — of African or Scandinavian ancestry. I had no symptoms.

The American Cancer Society recommend that men wait until the age of 50 to have a PSA test, but Stiller insists that his tumour would have worsened to the point of no return if he had waited that long.

Now healthy, Stiller is set to star in a new collaboration comedy drama with Noah Baumbach called Yeh Din Ka Kissa, and a biopic of the founder of the Chippendales, both to be released in 2017.
